3 Rewritten sessionsetup support, including support for legacy SMB
4 session setup needed for OS/2 and older servers such as Windows 95 and 98.
8 POSIX locking to servers which support CIFS POSIX Extensions
9 (disabled by default controlled by proc/fs/cifs/Experimental).
10 Handle conversion of long share names (especially Asian languages)
11 to Unicode during mount. Fix memory leak in sess struct on reconnect.
12 Fix rare oops after acpi suspend. Fix O_TRUNC opens to overwrite on
13 cifs open which helps rare case when setpathinfo fails or server does
18 Fix slow oplock break when mounted to different servers at the same time and
19 the tids match and we try to find matching fid on wrong server. Fix read
20 looping when signing required by server (2.6.16 kernel only). Fix readdir
21 vs. rename race which could cause each to hang. Return . and .. even
22 if server does not. Allow searches to skip first three entries and
23 begin at any location. Fix oops in find_writeable_file.
27 Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
28 configure stronger authentication. Fix sfu symlinks so they can
29 be followed (not just recognized). Fix wraparound of bcc on
30 read responses when buffer size over 64K and also fix wrap of
31 max smb buffer size when CIFSMaxBufSize over 64K. Fix oops in
32 cifs_user_read and cifs_readpages (when EAGAIN on send of smb
33 on socket is returned over and over). Add POSIX (advisory) byte range
34 locking support (requires server with newest CIFS UNIX Extensions
35 to the protocol implemented). Slow down negprot slightly in port 139
36 RFC1001 case to give session_init time on buggy servers.
40 Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
41 of readpages by eliminating one extra memcpy. Allow update of file size
42 from remote server even if file is open for write as long as mount is
43 directio. Recognize share mode security and send NTLM encrypted password
44 on tree connect if share mode negotiated.
48 Defer close of a file handle slightly if pending writes depend on that handle
49 (this reduces the EBADF bad file handle errors that can be logged under heavy
50 stress on writes). Modify cifs Kconfig options to expose CONFIG_CIFS_STATS2
51 Fix SFU style symlinks and mknod needed for servers which do not support the
52 CIFS Unix Extensions. Fix setfacl/getfacl on bigendian. Timeout negative
53 dentries so files that the client sees as deleted but that later get created
54 on the server will be recognized. Add client side permission check on setattr.
55 Timeout stuck requests better (where server has never responded or sent corrupt
60 Fix tcp socket retransmission timeouts (e.g. on ENOSPACE from the socket)
61 to be smaller at first (but increasing) so large write performance performance
62 over GigE is better. Do not hang thread on illegal byte range lock response
63 from Windows (Windows can send an RFC1001 size which does not match smb size) by
64 allowing an SMBs TCP length to be up to a few bytes longer than it should be.
65 wsize and rsize can now be larger than negotiated buffer size if server
66 supports large readx/writex, even when directio mount flag not specified.
67 Write size will in many cases now be 16K instead of 4K which greatly helps
68 file copy performance on lightly loaded networks. Fix oops in dnotify
69 when experimental config flag enabled. Make cifsFYI more granular.
73 Fix readdir caching when unlink removes file in current search buffer,
74 and this is followed by a rewind search to just before the deleted entry.
75 Do not attempt to set ctime unless atime and/or mtime change requested
76 (most servers throw it away anyway). Fix length check of received smbs
77 to be more accurate. Fix big endian problem with mapchars mount option,
78 and with a field returned by statfs.
82 Add support for mounting to older pre-CIFS servers such as Windows9x and ME.
83 For these older servers, add option for passing netbios name of server in
84 on mount (servernetbiosname). Add suspend support for power management, to
85 avoid cifsd thread preventing software suspend from working.
86 Add mount option for disabling the default behavior of sending byte range lock
87 requests to the server (necessary for certain applications which break with
88 mandatory lock behavior such as Evolution), and also mount option for
89 requesting case insensitive matching for path based requests (requesting
90 case sensitive is the default).
94 Add writepage performance improvements. Fix path name conversions
95 for long filenames on mounts which were done with "mapchars" mount option
96 specified. Ensure multiplex ids do not collide. Fix case in which
97 rmmod can oops if done soon after last unmount. Fix truncated
98 search (readdir) output when resume filename was a long filename.
99 Fix filename conversion when mapchars mount option was specified and
100 filename was a long filename.
104 Fix error mapping of the TOO_MANY_LINKS (hardlinks) case.
105 Do not oops if root user kills cifs oplock kernel thread or
106 kills the cifsd thread (NB: killing the cifs kernel threads is not
107 recommended, unmount and rmmod cifs will kill them when they are
108 no longer needed). Fix readdir to ASCII servers (ie older servers
109 which do not support Unicode) and also require asterisk.
110 Fix out of memory case in which data could be written one page
111 off in the page cache.
115 Fix caching problem, in which readdir of directory containing a file
116 which was cached could cause the file's time stamp to be updated
117 without invalidating the readahead data (so we could get stale
118 file data on the client for that file even as the server copy changed).
119 Cleanup response processing so cifsd can not loop when abnormally
125 Fix oops in ls when Transact2 FindFirst (or FindNext) returns more than one
126 transact response for an SMB request and search entry split across two frames.
127 Add support for lsattr (getting ext2/ext3/reiserfs attr flags from the server)
128 as new protocol extensions. Do not send Get/Set calls for POSIX ACLs
129 unless server explicitly claims to support them in CIFS Unix extensions
130 POSIX ACL capability bit. Fix packet signing when multiuser mounting with
131 different users from the same client to the same server. Fix oops in
132 cifs_close. Add mount option for remapping reserved characters in
133 filenames (also allow recognizing files with created by SFU which have any
134 of these seven reserved characters, except backslash, to be recognized).
135 Fix invalid transact2 message (we were sometimes trying to interpret
136 oplock breaks as SMB responses). Add ioctl for checking that the
137 current uid matches the uid of the mounter (needed by umount.cifs).
138 Reduce the number of large buffer allocations in cifs response processing
139 (significantly reduces memory pressure under heavy stress with multiple
140 processes accessing the same server at the same time).
144 Fix updates of DOS attributes and time fields so that files on NT4 servers
145 do not get marked delete on close. Display sizes of cifs buffer pools in
146 cifs stats. Fix oops in unmount when cifsd thread being killed by
147 shutdown. Add generic readv/writev and aio support. Report inode numbers
148 consistently in readdir and lookup (when serverino mount option is
149 specified use the inode number that the server reports - for both lookup
150 and readdir, otherwise by default the locally generated inode number is used
151 for inodes created in either path since servers are not always able to
152 provide unique inode numbers when exporting multiple volumes from under one
157 Allow new nouser_xattr mount parm to disable xattr support for user namespace.
158 Do not flag user_xattr mount parm in dmesg. Retry failures setting file time
159 (mostly affects NT4 servers) by retry with handle based network operation.
160 Add new POSIX Query FS Info for returning statfs info more accurately.
161 Handle passwords with multiple commas in them.
165 Fix default mode in sysfs of cifs module parms. Remove old readdir routine.
166 Fix capabilities flags for large readx so as to allow reads larger than 64K.
170 Add module init parm for large SMB buffer size (to allow it to be changed
171 from its default of 16K) which is especially useful for large file copy
172 when mounting with the directio mount option. Fix oops after
173 returning from mount when experimental ExtendedSecurity enabled and
174 SpnegoNegotiated returning invalid error. Fix case to retry better when
175 peek returns from 1 to 3 bytes on socket which should have more data.
176 Fixed path based calls (such as cifs lookup) to handle path names
177 longer than 530 (now can handle PATH_MAX). Fix pass through authentication
178 from Samba server to DC (Samba required dummy LM password).
182 Turn off DNOTIFY (directory change notification support) by default
183 (unless built with the experimental flag) to fix hang with KDE
184 file browser. Fix DNOTIFY flag mappings. Fix hang (in wait_event
185 waiting on an SMB response) in SendReceive when session dies but
186 reconnects quickly from another task. Add module init parms for
187 minimum number of large and small network buffers in the buffer pools,
188 and for the maximum number of simultaneous requests.
192 Add setfacl support to allow setting of ACLs remotely to Samba 3.10 and later
193 and other POSIX CIFS compliant servers. Fix error mapping for getfacl
194 to EOPNOTSUPP when server does not support posix acls on the wire. Fix
195 improperly zeroed buffer in CIFS Unix extensions set times call.
199 Fix internationalization problem in cifs readdir with filenames that map to
200 longer UTF-8 strings than the string on the wire was in Unicode. Add workaround
201 for readdir to netapp servers. Fix search rewind (seek into readdir to return
202 non-consecutive entries). Do not do readdir when server negotiates
203 buffer size to small to fit filename. Add support for reading POSIX ACLs from
204 the server (add also acl and noacl mount options).
208 Optionally allow using server side inode numbers, rather than client generated
209 ones by specifying mount option "serverino" - this is required for some apps
210 to work which double check hardlinked files and have persistent inode numbers.
214 Multiple bigendian fixes. On little endian systems (for reconnect after
215 network failure) fix tcp session reconnect code so we do not try first
216 to reconnect on reverse of port 445. Treat reparse points (NTFS junctions)
217 as directories rather than symlinks because we can do follow link on them.
221 Add config option to enable XATTR (extended attribute) support, mapping
222 xattr names in the "user." namespace space to SMB/CIFS EAs. Lots of
223 minor fixes pointed out by the Stanford SWAT checker (mostly missing
224 or out of order NULL pointer checks in little used error paths).
228 Add new mount parm to control whether mode check (generic_permission) is done
229 on the client. If Unix extensions are enabled and the uids on the client
230 and server do not match, client permission checks are meaningless on
231 server uids that do not exist on the client (this does not affect the
232 normal ACL check which occurs on the server). Fix default uid
233 on mknod to match create and mkdir. Add optional mount parm to allow
234 override of the default uid behavior (in which the server sets the uid
235 and gid of newly created files). Normally for network filesystem mounts
236 user want the server to set the uid/gid on newly created files (rather than
237 using uid of the client processes you would in a local filesystem).
241 Make transaction counts more consistent. Merge /proc/fs/cifs/SimultaneousOps
242 info into /proc/fs/cifs/DebugData. Fix oops in rare oops in readdir
243 (in build_wildcard_path_from_dentry). Fix mknod to pass type field
244 (block/char/fifo) properly. Remove spurious mount warning log entry when
245 credentials passed as mount argument. Set major/minor device number in
246 inode for block and char devices when unix extensions enabled.
250 Fix /proc/fs/cifs/Stats and DebugData display to handle larger
251 amounts of return data. Properly limit requests to MAX_REQ (50
252 is the usual maximum active multiplex SMB/CIFS requests per server).
253 Do not kill cifsd (and thus hurt the other SMB session) when more than one
254 session to the same server (but with different userids) exists and one
255 of the two user's smb sessions is being removed while leaving the other.
256 Do not loop reconnecting in cifsd demultiplex thread when admin
257 kills the thread without going through unmount.
261 Do not rename hardlinked files (since that should be a noop). Flush
262 cached write behind data when reopening a file after session abend,
263 except when already in write. Grab per socket sem during reconnect
264 to avoid oops in sendmsg if overlapping with reconnect. Do not
265 reset cached inode file size on readdir for files open for write on
271 Update number of blocks in file so du command is happier (in Linux a fake
272 blocksize of 512 is required for calculating number of blocks in inode).
273 Fix prepare write of partial pages to read in data from server if possible.
274 Fix race on tcpStatus field between unmount and reconnection code, causing
275 cifsd process sometimes to hang around forever. Improve out of memory
276 checks in cifs_filldir
280 Fix incorrect file size in file handle based setattr on big endian hardware.
281 Fix oops in build_path_from_dentry when out of memory. Add checks for invalid
282 and closing file structs in writepage/partialpagewrite. Add statistics
283 for each mounted share (new menuconfig option). Fix endianness problem in
284 volume information displayed in /proc/fs/cifs/DebugData (only affects
285 affects big endian architectures). Prevent renames while constructing
286 path names for open, mkdir and rmdir.
290 Change to mempools for alloc smb request buffers and multiplex structs
291 to better handle low memory problems (and potential deadlocks).
295 Fix incomplete listings of large directories on Samba servers when Unix
296 extensions enabled. Fix oops when smb_buffer can not be allocated. Fix
297 rename deadlock when writing out dirty pages at same time.
301 Fix open of files in which O_CREATE can cause the mode to change in
302 some cases. Fix case in which retry of write overlaps file close.
303 Fix PPC64 build error. Reduce excessive stack usage in smb password
304 hashing. Fix overwrite of Linux user's view of file mode to Windows servers.
308 Fixes for large file copy, signal handling, socket retry, buffer
309 allocation and low memory situations.
313 Better port 139 support to Windows servers (RFC1001/RFC1002 Session_Initialize)
314 also now allowing support for specifying client netbiosname. NT4 support added.
318 Fix reconnection (and certain failed mounts) to properly wake up the
319 blocked users thread so it does not seem hung (in some cases was blocked
320 until the cifs receive timeout expired). Fix spurious error logging
321 to kernel log when application with open network files killed.
325 Fix /proc/fs module unload warning message (that could be logged
326 to the kernel log). Fix intermittent failure in connectathon
327 test7 (hardlink count not immediately refreshed in case in which
328 inode metadata can be incorrectly kept cached when time near zero)
332 Allow file_mode and dir_mode (specified at mount time) to be enforced
333 locally (the server already enforced its own ACLs too) for servers
334 that do not report the correct mode (do not support the
335 CIFS Unix Extensions).
339 Fix some small memory leaks in some unmount error paths. Fix major leak
340 of cache pages in readpages causing multiple read oriented stress
341 testcases (including fsx, and even large file copy) to fail over time.
345 Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated with server.
346 This allows files that differ only in case and improves performance of file
347 creation and file open to such servers. Fix semaphore conflict which causes
348 slow delete of open file to Samba (which unfortunately can cause an oplock
349 break to self while vfs_unlink held i_sem) which can hang for 20 seconds.
353 fixes to cifs_readpages for fsx test case
357 Fix caching data integrity bug when extending file size especially when no
358 oplock on file. Fix spurious logging of valid already parsed mount options
359 that are parsed outside of the cifs vfs such as nosuid.
364 Connect to server when port number override not specified, and tcp port
365 unitialized. Reset search to restart at correct file when kernel routine
366 filldir returns error during large directory searches (readdir).
370 Fix caching problem when files opened by multiple clients in which
371 page cache could contain stale data, and write through did
372 not occur often enough while file was still open when read ahead
373 (read oplock) not allowed. Treat "sep=" when first mount option
374 as an override of comma as the default separator between mount
379 Allow passwords longer than 16 bytes. Allow null password string.
383 Gracefully clean up failed mounts when attempting to mount to servers such as
384 Windows 98 that terminate tcp sessions during protocol negotiation. Handle
385 embedded commas in mount parsing of passwords.
389 Invalidate local inode cached pages on oplock break and when last file
390 instance is closed so that the client does not continue using stale local
391 copy rather than later modified server copy of file. Do not reconnect
392 when server drops the tcp session prematurely before negotiate
393 protocol response. Fix oops in reopen_file when dentry freed. Allow
394 the support for CIFS Unix Extensions to be disabled via proc interface.
398 Fix hang in commit_write during reconnection of open files under heavy load.
399 Fix unload_nls oops in a mount failure path. Serialize writes to same socket
400 which also fixes any possible races when cifs signatures are enabled in SMBs
401 being sent out of signature sequence number order.
405 Fix byte range locking bug (endian problem) causing bad offset and
410 Fix oops (in send_sig) caused by CIFS unmount code trying to
411 wake up the demultiplex thread after it had exited. Do not log
412 error on harmless oplock release of closed handle.
416 Fix unsafe global variable usage and password hash failure on gcc 3.3.1
417 Fix problem reconnecting secondary mounts to same server after session
418 failure. Fix invalid dentry - race in mkdir when directory gets created
419 by another client between the lookup and mkdir.
423 Fix to list processing in reopen_files. Fix reconnection when server hung
424 but tcpip session still alive. Set proper timeout on socket read.
428 Add missing mount options including iocharset. SMP fixes in write and open.
429 Fix errors in reconnecting after TCP session failure. Fix module unloading
430 of default nls codepage
434 Active smb transactions should never go negative (fix double FreeXid). Fix
435 list processing in file routines. Check return code on kmalloc in open.
436 Fix spinlock usage for SMP.
440 Fix oops in reopen_files when invalid dentry. drop dentry on server rename
441 and on revalidate errors. Fix cases where pid is now tgid. Fix return code
442 on create hard link when server does not support them.
446 Fix scheduling while atomic error in getting inode info on newly created file.
447 Fix truncate of existing files opened with O_CREAT but not O_TRUNC set.
451 Fix oops on write to dead tcp session. Remove error log write for case when file open
452 O_CREAT but not O_EXCL
456 Fix non-POSIX behavior on rename of open file and delete of open file by taking
457 advantage of trans2 SetFileInfo rename facility if available on target server.
458 Retry on ENOSPC and EAGAIN socket errors.
462 Fix oops on big endian readdir. Set blksize to be even power of two (2**blkbits) to fix
463 allocation size miscalculation. After oplock token lost do not read through
468 Fix oops on empty file readahead. Fix for file size handling for locally cached files.
472 Fix oops in mkdir when server fails to return inode info. Fix oops in reopen_files
473 during auto reconnection to server after server recovered from failure.
477 Finish support for Linux 2.5 open/create changes, which removes the
478 redundant NTCreate/QPathInfo/close that was sent during file create.
479 Enable oplock by default. Enable packet signing by default (needed to
480 access many recent Windows servers)
484 Fix oops when mounting to long server names caused by inverted parms to kmalloc.
485 Fix MultiuserMount (/proc/fs/cifs configuration setting) so that when enabled
486 we will choose a cifs user session (smb uid) that better matches the local
487 uid if a) the mount uid does not match the current uid and b) we have another
488 session to the same server (ip address) for a different mount which
489 matches the current local uid.
493 Add support for mknod of block or character devices. Fix oplock
494 code (distributed caching) to properly send response to oplock
499 Finish up CIFS packet digital signing for the default
500 NTLM security case. This should help Windows 2003
501 network interoperability since it is common for
502 packet signing to be required now. Fix statfs (stat -f)
503 which recently started returning errors due to
504 invalid value (-1 instead of 0) being set in the
505 struct kstatfs f_ffiles field.
509 Fix oops on stopping oplock thread when removing cifs when
514 Fix mount options for ro (readonly), uid, gid and file and directory mode.
518 Fix errors displayed on failed mounts to be more understandable.
519 Fixed various incorrect or misleading smb to posix error code mappings.
523 Fix display of NTFS DFS junctions to display as symlinks.
524 They are the network equivalent. Fix oops in
525 cifs_partialpagewrite caused by missing spinlock protection
526 of openfile linked list. Allow writebehind caching errors to
527 be returned to the application at file close.
531 Clean up options displayed in /proc/mounts by show_options to
532 be more consistent with other filesystems.
536 Fix delete of readonly file to Windows servers. Reflect
537 presence or absence of read only dos attribute in mode
538 bits for servers that do not support CIFS Unix extensions.
539 Fix shortened results on readdir of large directories to
540 servers supporting CIFS Unix extensions (caused by
541 incorrect resume key).
545 Fix truncate bug (set file size) that could cause hangs e.g. running fsx
549 unload nls if mount fails.
553 Add resume key support to search (readdir) code to workaround
554 Windows bug. Add /proc/fs/cifs/LookupCacheEnable which
555 allows disabling caching of attribute information for
560 Add more oplock handling (distributed caching code). Remove
561 dead code. Remove excessive stack space utilization from
566 Fix oops in get dfs referral (triggered when null path sent in to
567 mount). Add support for overriding rsize at mount time.
571 Fix buffer overrun in readdir which caused intermittent kernel oopses.
572 Fix writepage code to release kmap on write data. Allow "-ip=" new
573 mount option to be passed in on parameter distinct from the first part
574 (server name portion of) the UNC name. Allow override of the
575 tcp port of the target server via new mount option "-port="
579 Fix search handle leak on rewind. Fix setuid and gid so that they are
580 reflected in the local inode immediately. Cleanup of whitespace
581 to make 2.4 and 2.5 versions more consistent.
586 Fix signal sending so that captive thread (cifsd) exits on umount
587 (which was causing the warning in kmem_cache_free of the request buffers
588 at rmmod time). This had broken as a sideeffect of the recent global
589 kernel change to daemonize. Fix memory leak in readdir code which
590 showed up in "ls -R" (and applications that did search rewinding).
594 Reconnect tids and fids after session reconnection (still do not
595 reconnect byte range locks though). Fix problem caching
596 lookup information for directory inodes, improving performance,
597 especially in deep directory trees. Fix various build warnings.
601 Finish fixes to commit write for caching/readahead consistency. fsx
602 now works to Samba servers. Fix oops caused when readahead
603 was interrupted by a signal.
607 Fix data corruption (in partial page after truncate) that caused fsx to
608 fail to Windows servers. Cleaned up some extraneous error logging in
609 common error paths. Add generic sendfile support.
613 Fix memory leak in AllocMidQEntry.
614 Finish reconnection logic, so connection with server can be dropped
615 (or server rebooted) and the cifs client will reconnect.
619 Fix temporary socket leak when bad userid or password specified
620 (or other SMBSessSetup failure). Increase maximum buffer size to slightly
621 over 16K to allow negotiation of up to Samba and Windows server default read
622 sizes. Add support for readpages
626 Fix oops when username not passed in on mount. Extensive fixes and improvements
627 to error logging (strip redundant newlines, change debug macros to ensure newline
628 passed in and to be more consistent). Fix writepage wrong file handle problem,
629 a readonly file handle could be incorrectly used to attempt to write out
630 file updates through the page cache to multiply open files. This could cause
631 the iozone benchmark to fail on the fwrite test. Fix bug mounting two different
632 shares to the same Windows server when using different usernames
633 (doing this to Samba servers worked but Windows was rejecting it) - now it is
634 possible to use different userids when connecting to the same server from a
635 Linux client. Fix oops when treeDisconnect called during unmount on
636 previously freed socket.
640 Fix oops in readpages caused by not setting address space operations in inode in
645 Includes support for deleting of open files and renaming over existing files (per POSIX
646 requirement). Add readlink support for Windows junction points (directory symlinks).
650 Changed read and write to go through pagecache. Added additional address space operations.
651 Memory mapped operations now working.
655 Added writepage code for additional memory mapping support. Fixed leak in xids causing
656 the simultaneous operations counter (/proc/fs/cifs/SimultaneousOps) to increase on
657 every stat call. Additional formatting cleanup.
661 Fix bigendian bug in order of time conversion. Merge 2.5 to 2.4 version. Formatting cleanup.
665 Fixes from Zwane Mwaikambo for adding missing return code checking in a few places.
666 Also included a modified version of his fix to protect global list manipulation of
667 the smb session and tree connection and mid related global variables.
671 Fix problem with captive thread hanging around at unmount time. Adjust to 2.5.42-pre
672 changes to superblock layout. Remove wasteful allocation of smb buffers (now the send
673 buffer is reused for responses). Add more oplock handling. Additional minor cleanup.
677 More stylistic updates to better match kernel style. Add additional statistics
678 for filesystem which can be viewed via /proc/fs/cifs. Add more pieces of NTLMv2
679 and CIFS Packet Signing enablement.
683 Replace call to sleep_on with safer wait_on_event.
684 Make stylistic changes to better match kernel style recommendations.
685 Remove most typedef usage (except for the PDUs themselves).
689 Update mount so the -unc mount option is no longer required (the ip address can be specified
690 in a UNC style device name. Implementation of readpage/writepage started.
694 Fix intermittent problem with incorrect smb header checking on badly
695 fragmented tcp responses
699 Fixes to setting of allocation size and file size.
703 Various 2.5.38 fixes. Now works on 2.5.38
707 Prepare for 2.5 kernel merge. Remove ifdefs.
711 Socket buffer management fixes. Fix dual free.
715 Various big endian fixes for hardlinks and symlinks and also for dfs.
719 Various big endian fixes for servers with Unix extensions such as Samba
723 Various FindNext fixes for incorrect filenames on large directory searches on big endian
724 clients. basic posix file i/o tests now work on big endian machines, not just le
728 SessionSetup and NegotiateProtocol now work from Big Endian machines.
729 Various Big Endian fixes found during testing on the Linux on 390. Various fixes for compatibility with older
730 versions of 2.4 kernel (now builds and works again on kernels at least as early as 2.4.7).
734 Various minor fixes for Connectathon Posix "basic" file i/o test suite. Directory caching fixed so hardlinked
735 files now return the correct number of links on fstat as they are repeatedly linked and unlinked.
739 Implemented "Raw" (i.e. not encapsulated in SPNEGO) NTLMSSP (i.e. the Security Provider Interface used to negotiate
740 session advanced session authentication). Raw NTLMSSP is preferred by Windows 2000 Professional and Windows XP.
741 Began implementing support for SPNEGO encapsulation of NTLMSSP based session authentication blobs
742 (which is the mechanism preferred by Windows 2000 server in the absence of Kerberos).
746 Introduced optional mount helper utility mount.cifs and made coreq changes to cifs vfs to enable
747 it. Fixed a few bugs in the DFS code (e.g. bcc two bytes too short and incorrect uid in PDU).
751 Rewrote much of connection and mount/unmount logic to handle bugs with
752 multiple uses to same share, multiple users to same server etc.
756 Fixed major problem with dentry corruption (missing call to dput)
760 Rewrite of readdir code to fix bug. Various fixes for bigendian machines.
761 Begin adding oplock support. Multiusermount and oplockEnabled flags added to /proc/fs/cifs
762 although corresponding function not fully implemented in the vfs yet
766 Fixed dentry caching bug, misc. cleanup
770 Fixed 2.5 support to handle build and configure changes as well as misc. 2.5 changes. Now can build
771 on current 2.5 beta version (2.5.24) of the Linux kernel as well as on 2.4 Linux kernels.
772 Support for STATUS codes (newer 32 bit NT error codes) added. DFS support begun to be added.
776 Unix extensions (symlink, readlink, hardlink, chmod and some chgrp and chown) implemented
777 and tested against Samba 2.2.5
782 1) Fixed lockrange to be correct (it was one byte too short)
784 2) Fixed GETLK (i.e. the fcntl call to test a range of bytes in a file to see if locked) to correctly
785 show range as locked when there is a conflict with an existing lock.
787 3) default file perms are now 2767 (indicating support for mandatory locks) instead of 777 for directories
788 in most cases. Eventually will offer optional ability to query server for the correct perms.
790 3) Fixed eventual trap when mounting twice to different shares on the same server when the first succeeded
791 but the second one was invalid and failed (the second one was incorrectly disconnecting the tcp and smb
794 4) Fixed error logging of valid mount options
796 5) Removed logging of password field.
798 6) Moved negotiate, treeDisconnect and uloggoffX (only tConx and SessSetup remain in connect.c) to cifssmb.c
799 and cleaned them up and made them more consistent with other cifs functions.
801 7) Server support for Unix extensions is now fully detected and FindFirst is implemented both ways
802 (with or without Unix extensions) but FindNext and QueryPathInfo with the Unix extensions are not completed,
803 nor is the symlink support using the Unix extensions
805 8) Started adding the readlink and follow_link code
